The correct answer as to how Prohibition contributed to the growth of organized crime is B. by making it easier for bootleggers to branch into other types of illegal activity. Given that alcohol was prohibited at the time, bootleggers could expand their illegal activities to alcohol now as well. Previously, there was no need to illegally import alcohol as it was allowed, however, after the Prohibition, many people still wanted to drink even though it was forbidden. This is why they went to bootleggers, whose business boomed.
